166 THE GENESIS OF SCIENCE. 



other, and showing how it gradually came to be distin 

 guishable from the other. We may expect to find theii 

 generalizations essentially artificial ; and we shall not be 

 deceived. Some illustrations of this may here be fitly in 

 troduced, by way of preliminary to a brief sketch of the 

 genesis of science from the point of view indicated. And 

 we cannot more readily find such illustrations than by 

 glancing at a few of the various classifications of the sci 

 ences that have from time to time been proposed. To con 

 sider all of them would take too much space : we must 

 content ourselves with some of the latest. 



Commencing with those which may be soonest disposed 

 of, let us notice first the arrangement propounded by Oken 

 An abstract of it runs thus : 



Part I. MATIIESIS. Pncvmatogcny : Primary Art, Primary 

 Consciousness, God, Primary Eest, Time, Polarity, Mo 

 tion, Man, Space, Point, Line, Surface, Globe, Eotation. 

 Hylogeny : Gravity, Matter, Ether, Heavenly Bodies, 

 Light, Heat, Fire. 



(He explains that MATHESIS is the doctrine of the whole ; 

 Pneumatogeny being the doctrine of immaterial totalities, and 

 Hylogeny that of material totalities.) 



Part II. ONTOLOGY. Cosmogeny : Eest, Centre, Motion, Line, 

 Planets, Form, Planetary System, Comets. StiJcMo- 

 geny : Condensation, Simple Matter, Elements, Air, 

 &quot;Water, Earth. StiJcliiology : Functions of the Elements, 

 &c. &c. Kingdoms of Nature : Individuals. 



(He says in explanation that &quot; ONTOLOGY teaches us the 

 phenomena of matter. The first of these are the heavenly 

 bodies comprehended by Cosmogeny. These divide into ele 

 ments Stijchiogeny, The eartli element divides into miner 

 als Mineralogy. These unite into one collective body 

 Geogeny. The whole in singulars is the living, or Organic,
